terrestrial mollusca inhabiting society islands. 
It has tisually been confounded with papillata, a much larger species, measuring 
15 mill in length, and a well-characterized papillary apex. Ihe shell now under 
consideration is only 1‘2 mill, long, the same as stated in Pfeiffer’s description.

This fine large species is peculiar to Raiatea, where it inhabits moist grounds in 
the upper portions of the central valleys, both on the east and west coasts. It is not 
by any means common. 
Dr. Pfeiffer, on the authority of Mr. Cuming, gives the wrong habitat “ Tahiti.” 
It was, doubtless, collected by the latter at Raiatea, and, as was too frequently the 
case, he gave the above erroneous locality. 
It is the only species I know, inhabiting this group, which agrees closely in all its 
specific characters with papillata as described by Dr. Pfeiffer. Mr. Pease, on the 
contrary, considered the preceding species to be the true papillata, notwithstanding 
the latter is stated to be 15 mill, in length, whilst the Iluaheine shell is only 12, and 
invariably shows two and a half whorls. The papillata has two whorls only and the 
spire is conspicuously papillary ; and Pfeiffer’s “ margine dextro superne curvato” 
accords better with tliis species than with the Huaheine shell. 
1 he color is reddish amber, rarely whitish or light corneous. Sometimes, though 
rarely, there is slight indication of a depression on the upper portion of the body-wliorl, 
and more Irequently the surface is slightly impressed transversely, a character common 
to neaily all the species inhabiting the group. They vary in shape, as the following 
measurements will show ; — 
Length 18, diam. 12, height 6^, spire 5 mill. 
Length 17, diam. 11, height 6, spire 6 mill. 
Length 14, diam. 8, height 5, spire 5 mill.
